A human brain weighs about 1 kg and contains about 10"
Chapter 1, Problem 95P(choose chapter or problem)
A human brain weighs about 1 kg and contains about \(10^{11}\) cells. Assuming that each cell is completely filled with water (density = 1 g/mL), calculate the length of one side of such a cell if it were a cube. If the cells are spread out in a thin layer that is a single cell thick, what is the surface area in square meters?

QUESTION:
A human brain weighs about 1 kg and contains about \(10^{11}\) cells. Assuming that each cell is completely filled with water (density = 1 g/mL), calculate the length of one side of such a cell if it were a cube. If the cells are spread out in a thin layer that is a single cell thick, what is the surface area in square meters?
ANSWER:Step 1 of 4
Here, we are going to find out the surface area of each cell.
Weight of human brain = 1 kg =1000 g contains = cells
Density of water = 1.0 g/mL
The mass of a brain cell is: = g/cells
